What Is Health Informatics? A Growing Career Path in Healthcare Technology

Healthcare runs on data now. Hospitals, clinics, and public health agencies all depend on digital systems to manage patient information, track health trends, and support the decisions clinicians make every day. Health informatics is the field that makes those systems work.

For students who like healthcare but are also drawn to technology, data, or problem-solving, it’s worth a closer look.

What Is Health Informatics?

Health informatics is the use of data, information systems, and technology to support healthcare. It covers how health information gets collected, stored, shared, analyzed, and used, drawing on healthcare knowledge, computer systems, and data analysis all at once.

The goal isn’t to collect more information for its own sake. It’s to help healthcare organizations turn raw data into something people can actually use to make better decisions.

How Is Health Informatics Used in Healthcare?

Some of these tools are visible to patients. Most work quietly in the background.

Electronic Health Records

Electronic health records, or EHRs, let healthcare organizations store and retrieve patient information digitally. Health informatics professionals often help implement and maintain these systems, then train staff to use them well and spot places where the workflow could improve.

Healthcare Data Analytics

Healthcare organizations collect enormous amounts of information about patients, treatments, and outcomes. Data analytics turns that volume into something usable: patterns, performance measures, decisions clinicians and administrators can act on.

Clinical Decision Support

Some healthcare technologies give clinicians information right when they need it. These systems organize relevant data, send alerts, or surface important details faster. Health informatics professionals design, test, and maintain these tools.

Telehealth and Remote Monitoring

Telehealth platforms, mobile health apps, and connected devices have opened up new ways to collect and share health information. Health informatics helps organizations manage that data and connect it to other systems, all while protecting accuracy and privacy.

Data Privacy and Security

Patient health information is sensitive. It has to be handled carefully. Professionals working with health data systems support privacy practices, data governance, and appropriate access to records, often in close collaboration with IT, compliance, and clinical teams.

What Do Health Informatics Professionals Do?

Responsibilities vary widely depending on the employer and the role. Some professionals focus almost entirely on technology systems. Others spend most of their time analyzing data or supporting clinical teams directly.

Common responsibilities can include:

• Managing or supporting electronic health record systems
• Reviewing and analyzing clinical data
• Creating reports for healthcare teams or administrators
• Checking data for accuracy and completeness
• Improving healthcare workflows
• Supporting new technology rollouts
• Maintaining healthcare databases
• Protecting confidential patient information
• Training staff on information systems
• Coordinating across clinical, administrative, and technical teams

The U.S. Bureau of Labor Statistics notes that health information technologists and medical registrars often advise organizations on computerized healthcare systems and analyze clinical data, with some specializing in EHRs and others using healthcare data for research or program evaluation.

Is Health Informatics the Same as Health Information Management?

Not quite, though the two overlap.

Health information management typically focuses on maintaining, organizing, and protecting patient records. Health informatics puts more weight on using technology and data to support the broader flow of information across a healthcare system, including analysis and decision-making.

Because responsibilities and terminology can differ between programs and employers, students comparing the two should look closely at individual academic programs and job descriptions rather than assume the terms are interchangeable.

What Skills Are Important in Health Informatics?

Analytical thinking. Working with healthcare data means spotting patterns, reviewing results, and explaining what the numbers actually mean.

Attention to detail. Accuracy matters when the data involves patient records. Missing or inconsistent information can affect reports, research, and operations before anyone notices.

Technology skills. Requirements vary by role, but professionals often work with databases, EHRs, reporting software, and analytics tools. Understanding how different systems share information matters just as much as knowing any one system well.

Healthcare knowledge. This isn’t purely an IT field. Knowing healthcare terminology, clinical workflows, and privacy practices helps professionals understand how the technology actually affects the people using it.

Problem-solving. System issues and process gaps come up constantly, and fixing them usually takes looking at the problem from both a healthcare and a technology angle.

Communication. Health informatics professionals work across clinicians, administrators, analysts, and IT specialists, groups that don’t always share the same vocabulary or priorities. Being able to bridge that gap is a real skill.

The Bureau of Labor Statistics lists analytical skills, attention to detail, integrity, interpersonal skills, and problem-solving among the qualities that matter most for health information technologists and medical registrars.

Career Outlook: Growth, Roles, and Where Professionals Work

The volume of digital health information keeps growing, and that’s driving demand for people who can manage it. The Bureau of Labor Statistics projects employment of health information technologists and medical registrars to grow about 16% from 2025 to 2035, compared with 3% for all occupations, with about 3,000 openings projected each year on average.

Part of that growth comes from technology itself changing. Artificial intelligence, telehealth, mobile health tools, and the push toward better interoperability between systems are reshaping what health informatics work looks like year to year.

Because the field connects healthcare, technology, and data, it opens the door to a range of roles:

• Health information technologist
• Health informatics specialist
• Clinical informatics specialist
• Health data analyst
• Clinical data analyst
• Electronic health record specialist
• Health information systems specialist
• Healthcare IT project professional
• Informatics nurse
• Healthcare technology consultant

Hospitals are the largest employer for health information technologists and medical registrars specifically, according to current BLS data. Physicians’ offices, management companies, and professional and technical services firms also hire for related roles. Job titles, requirements, and education expectations vary between employers. Some positions typically require an associate degree; others call for a bachelor’s degree or higher, and employers may prefer certification on top of that. A degree alone doesn’t guarantee a specific role. Outcomes depend on experience, technical skills, employer expectations, location, and any additional credentials the position requires.

Is This Career Path Right for You?

Health informatics tends to appeal to people who want healthcare work without focusing entirely on direct patient care. That includes students who like working with technology, analyzing data, or figuring out how a system could run better, and it also includes people who already have healthcare experience and want to build stronger technical or data skills on top of it. Someone who has spent years working with EHRs as a nurse, for example, might naturally get curious about how those systems get designed and improved in the first place.

There’s no single path into the field. People move into health informatics from backgrounds in health information management, IT, data analytics, computer science, healthcare administration, nursing, and public health. Useful areas of study tend to include healthcare systems, medical terminology, databases, statistics, and electronic health records. According to the Bureau of Labor Statistics, related academic programs often cover medical terminology, health data requirements, medical ethics, and coding and classification systems.

The right preparation depends on the specific role. A data-focused position calls for different training than one centered on clinical systems, so it’s worth comparing your own background against the job descriptions you’re actually interested in.

Explore Healthcare and Technology Education Options

As healthcare and technology keep converging, understanding how data supports healthcare organizations opens doors across several career paths.

For nurses, this connection is worth a second look. Informatics nurses are already one of the roles bridging clinical care and technology, and a BSN can help build the foundation for that kind of work. MDC Online’s RN to BSN program is designed for working RNs who want to grow their skill set and open up more of these technology-connected paths without stepping away from their current job.
